warn

open fun warn(message: () -> Any?)

open fun warn(throwable: Throwable?, message: () -> Any?)

open fun warn(throwable: Throwable?, marker: Marker?, message: () -> Any?)

Lazy add a log message if isWarnEnabled is true

open fun ~~warn~~(marker: Marker?, msg: () -> Any?)

Deprecated

use warn instead

Replace with

warn(null, marker, msg)

Lazy add a log message with a marker if isWarnEnabled is true

open fun ~~warn~~(marker: Marker?, t: Throwable?, msg: () -> Any?)

Deprecated

use warn instead

Replace with

warn(t, marker, msg)

open fun ~~warn~~(msg: String?)

Deprecated

Use warn {} instead

Log a message at the WARN level.

Parameters

msg

the message string to be logged

open fun ~~warn~~(msg: String?, arg: Any?)

Deprecated

Use warn {} instead

Replace with

warn { "$msg $arg"}

Log a message at the WARN level according to the specified msg and argument.

This form avoids superfluous object creation when the logger is disabled for the WARN level.

Parameters

msg

the msg string

arg

the argument

open fun ~~warn~~(msg: String?, vararg arguments: Any?)

Deprecated

Use warn {} instead

Replace with

warn { "$msg $arguments"}

Log a message at the WARN level according to the specified msg and arguments.

This form avoids superfluous string concatenation when the logger is disabled for the WARN level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for WARN. The variants taking .warn and .warn arguments exist solely in order to avoid this hidden cost.

Parameters

msg

the msg string

arguments

a list of 3 or more arguments

open fun ~~warn~~(msg: String?, arg1: Any?, arg2: Any?)

Deprecated

Use warn {} instead

Replace with

warn { "$msg $arg1 $arg2"}

Log a message at the WARN level according to the specified msg and arguments.

This form avoids superfluous object creation when the logger is disabled for the WARN level.

Parameters

msg

the msg string

arg1

the first argument

arg2

the second argument

open fun ~~warn~~(msg: String?, t: Throwable?)

Deprecated

Use warn {} instead

Replace with

warn(t) { "$msg"}

Log an exception (throwable) at the WARN level with an accompanying message.

Parameters

msg

the message accompanying the exception

the exception (throwable) to log

open fun ~~warn~~(marker: Marker?, msg: String?)
